FOLDING PAPER BOX.

Specification of Letters Patent.

Patented June 25, 1912.

Application filed September 5, 1911. Serial No. 647,749.

To all whom it may concern? Be it known that I, JEFFREY T. Fnnnns, a citizen of the United States, residing at Anderson, in the county of Madison and State of Indiana, have invented certain new and useful Improvements in Folding Paper Boxes, of which the following is a specification.

My invention relates to that class of boxes knownas folding paper boxes, preferably made of double faced corrugated paper board intended for the packaging and shipment of articles of different kinds.

The object of my invention is to so form or construct the box as to afford the great-- est strength and rigidity and at the same time to make the box more economical of manufacture than other boxes of the same general character. With this object in view I provide the four walls of a box with end extensions which are foldable inwardly in pairs upon each other, and form one set of these extensions at each end of the box with complementary inclined adjacent edges, such edges running diagonally of the ends of the box and across or at an angle to the corrugations of the other sets of extensions (where the material used is corrugated board) and which are foldable upon and secured to the first mentioned set. As the result these extensions which form the cover flaps or closures for the ends of the box are materially strengthened and the box made more rigid inasmuch as the seam or joint of the two innermost sets of flaps cross the line of corrugations of the outer sets of flaps in a diagonal line, it being understood that such seam or joint represents a weak place and also that corrugated paper board is weak in a direction parallel with the line of corrugations. Moreover this diagonal running of the seam or joint enables the outer sets of flaps to be glued thereto more securely inasmuch as there is then less tendency of the inner flaps being forced down particularly in the center away from the outer flaps in the gluing operation, with the result that the two sets of flaps are firmly secured to each other as to their entire area. Furthermore this construction of box results in economy of manufacture inasmuch as it enables the band saw which is commonly used in cutting blanks of this general character, to enter the blank from one side and to proceed directly into the body of the blank at an angle thereto instead of being first introduced along one of the cuts or slits in the blank which renders the cutting op eration more difficult and requires more time.

In the drawings Figure 1 is a plan view of a blank for a box embodying my invention; Fig. 2 a plan view of the complete box in flat or collapsed form; Fig. 3 a perspective of the complete box shown partly erected or assembled for use and Fig. 4 a plan view of the box illustrating one of the ends thereof.

The particular box shown is formed of double faced corrugated board which is the material preferably employed by me but it is to be understood that so far as my invention in its broader aspect is concerned other material may be employed. However, for the purposes of clear and definite disclosure of my invention I will describe the same in connection with the illustrated box as one embodiment of my invention.

Referring to the box as herein shown which may obviously be of any suitable shape and dimensions, the same comprises a series of four side walls 1, 2, 3 and 4:, which are hinged together upon the score lines indicated particularly in the blank illustrated in Fig. 1 and provided at their opposite ends with extensions 1*, 2 3 and 4 respectively. To form the box the outer edges of the walls 1 and 4 are brought together and held in hinged relationship in suitable manner as by means of the tape 5, Figs. 2 and 3.

The end extensions are foldable inwardly in pairs and constitute the end cover flaps or closures. As shown more particularly in Figs. 1, 3 and 4; the extensions or flaps 2 and 4e are rectangular and together equal in length the two opposite side walls 1 and 3 with the result that when the members of each pair or set of these flaps are folded inwardly and downwardly they together constitute a closed end or closure for each end, that is top and bottom, of the box. These sets of flaps 2 and P form the outer flaps in the completed box as indicated in Fig. 4, the same being foldable upon and secured to the other or inner sets of flaps now to be described.

The other sets of extensions or flaps 1 and 3 are in the present instance trapezoidal in form and are so out that when the members of each pair are brought together they will constitute a complete closure. The essential feature is that the meeting complementary edges 1 and 3 of these flaps shall be inclined or oblique so far as the other lines of the box are concerned, such edges being substantially diagonal with relation to the ends of the box. Moreover, when these flaps are folded together as in actual use the seam or joint bet-ween them will extend across or at an angle to the lines of corrugations 2 and 4 which are indicated in Fig. 3 whereby the end closures of the box are not weakened by the seams or joints of the inner set of flaps as they would be in case they ran straight across the ends of the box and therefore parallel with these corrugations.

As above stated, the two sets of flaps at each end of the box are secured together in suitable manner as by gluing or pasting and in this operation the particular construction above described, that is, the oblique or diagonal seams, are of much advantage inasmuch as they enable the sets of flaps to be securely glued together as to their entire surface or area whereas in the case of the old type of flaps the meeting ends or the central portions thereof would project inwardly of the'box and would therefore not become pasted or glued to the outer set of flaps. Furthermore, economy results from the construction of the box in the manner aboveexplained inasmuch as it enables the usual band saw to start at the very margins of the blank at the points indicated by the reference letter a in Fig. 1 instead of being first introduced inwardly of the blank along the slits or cuts therein.

I claim:

A folding box made of double faced corrugated paper board and comprising side walls hinged together each having end extensions foldable to form cover'fiaps' for the ends of the box, the extensions on two 0p posite walls having complementary adjacent edges which run at an angle to the corrugations of the other set of extensions the sets of extensions with the complementary edges being foldable inwardly and the remaining sets of extensions being foldable thereupon and secured thereto; substantially as described.
